Adder/Subtractor

Hello! friends

Welcome to my another Adder and Subtractor project. It's a topic of Digital And Logic Design by Morris Mano (fifth edition) with the help of this you'll know how its work in reality.

So let's get started.

With the help of this diagram we build our Adder/Subtractor project.

You'll need

Some pieces of wire

Soldering wire and solder

Vero board

Resistors: (330ohms x 13) and 1k

Ic's: lm7805, 74ls86 and 74ls38 with bases

Switches: spst x 9 and dpst x 1

Led's: red x 9 and yellow x 5

Place the components according to diagram on vero board and soldering it.

Here it is the soldering and jumper wires.

After its look like this.

When you push the switch on left side then its work as a adder and on left side as a subtractor you can see on image. I uploaded a video on next step i'm sure it will clear your concept.

Thanks for watching.

I hope you guys like it.
